Dynamic Evaluation of Motor Speech Skills (DEMSS) Manual

DEMSS is a dynamic assessment administered to preschool-aged children with severe speech sound disorders who have reduced phonemic and/or phonetic inventories, reduced vowel differentiation or frank vowel distortions, or little to no verbal output. The test is criterion-based and intended to diagnose severe speech sound disorders, judge just how severe the disorder is, and facilitate treatment plans and stimulus selection.
